What is a Coolant Flush?

disposing of old engine coolant the proper way

Yesterday we talked about radiators and how to stop radiator leaks. Today we’re going to talk about coolant flushes so you better understand the complete cycle of maintenance for radiators and engine cooling systems. With this information, you can protect your car from heat damage that can result in extremely costly repairs. Without it, you may find yourself stranded by the side of the road or, worse, stranded financially by auto repair bills.

Why Coolant Flushes Are Important

Engine coolant, oil, and a few fans are the only things keeping the engine from overheating while it explodes fire inside itself. Without engine coolant fluid to properly move heat away from the engine, it would get too hot for the oil which itself would lose its fluidity, dry up, and add to the overheating problem. The issue cascades further and further until one day your engine blows up and you’re stuck looking for a whole new car.

Don’t let this happen to you. You should get a coolant flush every two years or 30,000 miles, at least. More often if you drive more often or under harder conditions like off-road or load-hauling vehicles.

An additional perk of the coolant flushing process is that it helps wash away grime and small amounts of rust that have built up over time. And the engine conditioners added in help prevent them building up in the future. So there’s a large cumulative effect on the health of your engine from a coolant flush.

Signs You Need Coolant Flush Service

The most obvious signs that it’s time to get a coolant flush include:

  • Sweet smell, which comes from the ethylene glycol burning out of the antifreeze that’s mixed in with the engine coolant.

  • Engine temperature gauge reads high, and noticeably faster than it did before.

  • It’s been 2 years or 30,000 miles.

How It’s Done

First, we make sure the car hasn’t been running recently so we don’t burn ourselves when we open the radiator (pro-tip). Then:

  1. Pull the drain plug and drain the coolant and replace the plug.

  2. Fill the radiator with water then start the engine cycle it.

  3. Add a chemical engine flush to clean the system.

  4. Flush out the system with distilled water.

  5. Add coolant and antifreeze mixture.

  6. Add engine conditioners.

  7. Dispose of old fluids and chemicals safely and properly.

Of course, there’s some details missing from the process there, but that’s the gist. If you’re interested in learning more, check out this short video from ChrisFix who explains the coolant flush process with a visual aid to boot:

Getting a coolant flush is easy to forget about; heck, a lot of people these days don’t even know they need them. You, on the other hand, now know how a coolant flush works and when you need to do them so you won’t be left stranded on the side of the road, confused about how this happened to you. Just remember: every 2 years/30,000 miles, or if you otherwise suspect engine cooling system issues.
